CHARLES C. WICKWIRE, OF CORTLAND, NEW YORK.

SIEVE,

Application filed January 12, 1918.

To all whom it may concern:

Be it known that I, CHARLES C. VVIO wlnn, a citizen of the United States, residing at Cortland, in the county of Cortland and State of New York, have invented a certain new and useful Improvement in Sieves, of which the following is a specification.

My present invention pertains to sieves, and more particularly to a novel formation of the bails employed in conjunction there with for the reception of a bar or rod utilized to support the sieve.

The main object of the invention is to pro duce a bail from a single piece of wire and to so fashion it that it may be readily brought into. proper position with reference to the sieve and secured in place, and this without the employment of any extraneous fastening devices.

The invention is illustrated in the annexed drawings, wherein:

Figure l is a side elevation of a sieve or screen, with one of the bails shown face-on;

Fig. 2 a vertical sectional View, with one of the bails (that to the left) shown in its initial and unclamped position, while that to the right is secured in place; and

Fig. 3 a perspective view of one of the bails, with the clamping elements thereof in their initial form ready to be positioned on the sieve.

In the drawings, 1 denotes the body or side wall of the sieve, formed of a woven wire fabric or the like; 2 the upper hoop or rim; 3 the lower hoop or base, and 4 the bottom which is preferably formed of woven wire fabric the same as the body 1.

The upper and lower edges of the body fabric are clamped between the folds of the hoops, and the edge of the bottom is likewise clamped in the lower hoop.

Each of the bails, of which there are two, placed diametrically opposite each other, is formed from a single piece of wire bent to form. It may be said to comprise an elongated body composed of two parallel, or substantially parallel, strands 5, 6, connected at their lower ends by a cross-over upturned loop 7 while at the upper end of the body the strands merge into two alined eyes or loop-shaped elements, with the ends of the strands extending downwardly and then bent outwardly to produce fastening fingers. Stated more specifically, the upper end of each of the side strands 5 and 6 is Specification of Letters Patent.

first curved outwardly, as at 8, and then curved over, forming an eye 9 with that portion or descending element 10 of the wire opposite the curve 8 carried down without any curvature transversely, but with a slight curvature laterally, as at 11. Said elements 10 terminate in outwardly and upwardly inclined fingers 12. One of the eye portions 9 stands directly in front of the other, while the downgoing elements 10 lie parallel to the strands 5 and 6, this latter condition being effected by the curvature at 11, the descending or downgoing element at the right, Fig. 3, being bent back rearWar-dly from the plane of its eye or loop 9, while that at the left is carried forwardly; note Fig. 2.

The crown of each eye portion 9 will preferably be provided with a slight lateral offset, as at 13, the two offsets forming an opening through which a nail may be in serted and driven into a handle 14 passed through theeyes.

The bails when initially formed up in a suitable bending machine take the form shown in Fig. 3 and at the left in Fig. 2. In assembling, the ends of the fingers 12 are passed through the mesh in the body immediately below the lower edge of the up.- per rim 2, with the loop 7 below the lower rim or hoop A slight upward movement of the bail will then carry the parts to the positions shown at the left in Fig. 2, whereupon the fingers 12 and loop 7 will be driven or pressed down into close and intimate contact with. the metal rims or hoops, thereby firmly securing the bail to the sieve.

In pressing the loops and fingers to place, the metal hoops or rims will be slightly deformed; that is, they will be indented by the wire and likewise carried slightly out of the vertical at the points where the bails are secured. This arrangement is found to firmly hold the bails in place. Furthermore, by reason of the fact that the loops and fingers pass beneath the rims or hoops, any slipping or displacement of the bails, due to the action of the load of material which may be placed. in the sieve, is preeluded.

The structure has the advantage of being light and easy of formation and placement, and withal is cheap of construction.

Having thus described my invention, what I claim is:

1. In a sieve, the combination of abody portion; an upper and a lower rim; and a bail secured thereto, said bail being formed of a single piece of wire bent to form and comprising an upturned looped end, two side bars or strands and an eye carried at the upper end of each strand, said loops registering with each other and each loop terminating in a finger, said fingers passing through the sieve body and engaging the upper rim while the looped lower end engages the lower rim.

2. In a sieve, the combination of a reticulated body portion; an upper and a lower rim; and a pair of bails secured thereto, each bail being formed from a single piece of Wire bent to form and comprising an upturned looped end and two side bars or strands, said end and strands embracing the lower rim, an eye or loop formed upon the upper end of each strand, the eyes registering with each other, a downwardly-extending element formed as an extension from each eye, and a finger extending inwardly from each of such elements, said fingers passing through the reticulated body, the upper rim being embraced between said fingers and the side bars.

3. In a sieve, the combination of a body portion; an upper and a lower rim; and a pair of bails secured thereto, each bail being formed from a single piece of wire bent to form and comprising an element adapted to engage the lower rim, upwardly-extending side bars or strands, a pair of contacting and registering eyes formed at the upper ends of the strands, and attaching elements connected to the strands, said eyes or loops at their upper portions being outwardly curved or indented to form an opening for the reception of a nail or the like.

l. In a sieve, the combination of a body portion; an upper and a lower rim; and a pair of bails secured thereto, each bail being formed from a single piece of wire bent to form and comprising an upturned looped end, a pair of side bars or strands, said strands and loop engaging the lower rim, a pair of eyes or loops at the upper portion of the strands, said eyes being in registry and contacting with each other, an element or arm extending downwardly from each loop, said elements being brought into the same plane as that occupied by the side bars, and an inwardly and upwardly extending finger formed as an extension of each arm, the upper rim being embraced between said fingers and the arms and side bars or strands.

5. In combination with a sieve having upper and lower hoops, a air of bails secured thereto, each bail being formed from asingle piece of wire bent to form and comprising two strand body portions with an upturned connecting loop at their lower ends embracing the lower hoop, a pair of eyes at the upper ends of the strands, and fingers formed at the ends of the wire as it passes from the eyes, said fingers passing through the sieve body and contacting the inner face of the upper hoop.

6. As a new article of manufacture, a wire bail adapted to be secured to a sieve or the like, said bail being formed from a single piece of wire bent to form and comprising an upturned looped end, two bars or strands extending upwardly therefrom, an eye or loop formed upon the upper end of each strand, the eyes registering with each other, a downwardly-extending element formed as an extension from each eye, and a finger projecting inwardly from each of such elements, said fingers and the upturned loop forming supporting points between the bail and the article to which it is to be attached, and adapted to be bent into locking engagement therewith.

In testimony whereof I have signed my name to this specification.
